Benefits of Replacement Windows:

Replacement windows add significant value to your house not only by enhancing its curb appeal, but more importantly,
by improving your energy efficiency. According to the Energy Information Administration (EIA) and other sources,
significant heat loss occurs through windows and doors!

Making your home more energy efficient also boosts your home's resale value, so the likelihood that you will recoup
your costs is very high. One remodeling magazine stated in a "Cost vs. Value Report" published in 2007, that upscale
vinyl and midrange wood window replacements resulted in national recovery rates well above 70%. Replacement windows
are a truly solid investment.

Features to Consider When Buying Replacement Windows:

Definis and Sons installed windows feature a wide array of styles, decorative options, complementary trim selections
and performance packages for a fully customizable product to suit your personal style. Our windows offer the
ultimate choice for beauty, comfort and energy efficiency. They also help to pay for themselves through lower
energy cost, freedom from maintenance and increased property values!
